First you need to store the *unparsed* text as a string, byte array 
or some such thing. If you've already parsed it and thrown away the 
original, it's too late.

Then insert that string into your output message. All correct XML 
APIs I'm aware of will escape all the < and & signs as necessary to 
allow it top be treated as text. If you're using printf or 
System.out.println() or some such to generate your message, it's 
trickier. You can wrap the output in a CDATA section, but watch out 
for any embedded ]]> strings that may appear in the malformed input. 
If you see these, then you'll have to close the CDATA section, write 
]]&gt;, and then reopen the CDATA section.
